Description

Determination of passenger movement relative to elevator landing zone

Technical Field

The invention belongs to the technical field of Elevator (Elevator) intelligent control, and relates to a method for determining movement of passengers relative to an Elevator landing area by using wireless interaction between a wireless signal module installed in an Elevator car and a personal mobile terminal.

Background

In an existing elevator system, one of the common call operation modes is that a passenger manually presses a call button on a call control panel installed in an elevator landing area to input an up or down call request command, and then after entering a certain elevator car, the passenger manually presses a floor button on a destination floor registration control panel installed in each elevator car to input a destination floor. This call operation method requires manual operation, and particularly when the passenger's hands are not free to perform the above-described operation of pressing the buttons (for example, the passenger holds the items with both hands, or the passenger who is not walking well sits on a wheelchair), the call operation becomes difficult, which affects the passenger experience.

With the development of automatic call operation techniques, various techniques for automatically realizing call operations by a smart mobile terminal such as a mobile phone have come to be developed, but invalid calls are likely to be generated due to uncertainty in the movement or movement of passengers.

This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different processing devices and/or microcontroller devices.

In this specification, for convenience of description, "means for determining the movement of a passenger with respect to the elevator landing zone" will be simply referred to as "movement determination means", and "method for determining the movement of a passenger with respect to the elevator landing zone" will be simply referred to as "movement determination method".

FIG. 1 is a schematic diagram of an automatic call system in accordance with one embodiment of the present invention; fig. 2 is a schematic view illustrating an application scenario of a movement determination apparatus according to an embodiment of the present invention; fig. 3 is a schematic block diagram of a personal mobile terminal according to an embodiment of the present invention. A movement determining device, an automatic call system, an elevator system of an embodiment of the present invention are illustrated below in conjunction with fig. 1 and 3, while illustrating a method for determining movement of a passenger relative to an elevator landing zone.

The movement determination device 10 of the embodiment of the present invention is implemented in an automatic call system of the embodiment shown in fig. 1, thereby forming an automatic call system of an embodiment of the present invention, which is further applied to an elevator system 100 installed in a building, the elevator system 100 includes a plurality of one or more elevator cars 110 traveling up and down in a hoistway of the building, two of the elevator cars, i.e., 110-1 and 110-2, of the elevator system 100 are shown in fig. 1; the travel or stop of each elevator car 110 in the hoistway, i.e., each elevator car 110, is controlled by an elevator controller 140 in the elevator system 100, the particular manner or principle of control of one or more elevator cars 110 by the elevator controller 140 is not limiting, nor is the particular structure or arrangement of the elevator controller 140, etc.

It will be understood that the components or modules included in the movement-determining device 10 of the following embodiments of the present invention may be included in an automatic call system of an embodiment of the present invention, for example, an automatic call system including the first wireless signal module 130 and/or the second wireless signal module 120.

Continuing with fig. 1 and 2, the movement-determining device 10 includes one or more first wireless signal modules 130, each first wireless signal module 130 being mounted in each elevator car 110, e.g., one first wireless signal module 130-1 disposed in the elevator car 110-1 and one first wireless signal module 130-2 disposed in the elevator car 110-2. In one embodiment, the first wireless signal module 130 is mounted on and integrally disposed with the destination floor registration control panel in the elevator car 110, and the specific manner of integrating the first wireless signal module 130 with respect to the destination floor registration control panel is not limiting.

The first wireless signal module 130 may be specifically a Bluetooth Low Energy (BLE) module, and correspondingly, the first wireless signal is a Bluetooth Low Energy (Bluetooth Low Energy) signal. The first wireless signal module 130 transmits or broadcasts the first wireless signal, for example, continuously (e.g., at short intervals) and the signal strength of the broadcasted first wireless signal attenuates with the distance it is broadcasted, and the specific way of attenuation is not limited. The first wireless signal broadcast by the first wireless signal module 130 may be effective to substantially cover the area in the elevator car 110 in which it is installed, and the first wireless signal may be, for example, a bluetooth low energy signal, which may include a data signal of the first floor information in which the elevator car 110 is currently located, respectively.

It should be noted that the first wireless signal module 130 is coupled to the elevator controller 140, so that during the operation of each elevator car 110, the first wireless signal module 130 can obtain the information it wants from the elevator controller 140 in real time, for example, the current first floor information, the traveling direction information, etc. of the elevator car 110, and package the first floor information and/or the traveling direction information (the traveling direction information includes, for example, "traveling upwards", "traveling downwards", and "not traveling") as a wireless data signal to be broadcasted in the form of the first wireless signal.

Continuing with fig. 1-3, the movement determination apparatus 10 may also be implemented, at least in part, by a personal mobile terminal 200 carried by the passenger 90, each of the personal mobile terminals 200-1 and 200-2 carried by the two passengers, respectively, being capable of individually implementing at least part of the functionality of the movement determination apparatus 10. Each personal mobile terminal 200 is configured to be able to receive a first wireless signal broadcast by the first wireless signal module 130 when a distance condition is satisfied, as shown in fig. 3, a wireless communication module 210 in the personal mobile terminal 200, which is used for receiving the first wireless signal or other wireless signals, and the wireless communication module 210 may specifically be a bluetooth low energy module. The first wireless signal may include a data signal of information of a first floor where the elevator car 110 is currently located and/or information of a current traveling direction of the elevator car 110.

Each personal mobile terminal 200 is capable of determining the signal strength of the first wireless signal it receives, and in one embodiment, the signal strength determination module 230 in the personal mobile terminal 200 determines the signal strength of the received first wireless signal based on the first wireless signal. For example, the personal mobile terminal 200 is configured with a Received Signal Strength Indicator (RSSI) to determine the signal strength of the first wireless signal or any other wireless signal it receives, i.e. the signal strength determination module 230 is implemented by the RSSI.

It should be understood that the signal strength of the first wireless signal received by the personal mobile terminal 200 is related to the effective broadcasting distance of the first wireless signal or the strength of the broadcasting signal, which is set in advance. In one embodiment, by presetting the effective broadcast distance of the first wireless signal, for example, in a case where the individual mobile terminal 200 is less than or equal to 0.7-1 meter relative to the first wireless signal module 130, the signal strength of the first wireless signal received by the individual mobile terminal 200 will be greater than or equal to a first predetermined value, the RSSI may indicate that the signal strength of the first wireless signal is "strong", and 0.7-1 meter is for an effective broadcast distance. Therefore, the passenger 90 in the elevator car 110, whose personal mobile terminal 200 is carried by the passenger, can receive the relatively "strong" first wireless signal and can also obtain the first floor information broadcast in the first wireless signal at the same time, i.e., the personal mobile terminal 200 of the passenger 90 can obtain the first floor information of the current elevator car in real time.

The movement determination module 250 of the personal mobile terminal 200 of an embodiment of the present invention is used to determine the movement of the passenger 90 relative to the elevator landing zone 410 based on a change in the signal strength of the first wireless signal.

It should be noted that it is very meaningful to determine the movement of the passenger 90 relative to the elevator landing zone 410. This is because, with the development of elevator intelligent control technology, the personal mobile terminal 200 carried by the passenger 90 is an intelligent terminal that realizes automatic call operation, and can automatically issue various types of call operation commands, enabling the elevator controller to perform dispatching control of the elevator car, for example, automatically issuing a call command when the personal mobile terminal 200 is in the elevator landing zone 410 or close to the elevator landing zone 410, and the elevator controller will control the elevator car to run based on the call command; however, if the elevator car stops at a certain elevator landing zone, the personal mobile terminal 200 of the passenger coming out of the elevator car is likely to automatically give a call command, however, in most cases, the passenger coming out of the elevator car does not need to take the elevator again in a short time, and therefore, the call command in such a case does not really reflect the riding demand of the passenger. If the call command corresponding to a passenger 90 coming out of the elevator car is accepted by the elevator system, the elevator system is liable to be in an ineffective operation, seriously affecting the operation efficiency of the elevator system.

As shown in fig. 2, with the elevator car 110 traveling up or down to a floor N and stopping at the floor N, the floor N corresponding to, for example, an elevator landing zone 410, a passenger 90 carrying a personal mobile terminal 200 rides in the elevator car 110-1, the first wireless signal module 130-1 in the elevator car 110-1 broadcasts a first wireless signal all the time, which is received constantly by the personal mobile terminal 200 of one or more passengers 90 riding in the elevator. When the elevator car 110-1 reaches floor N and the landing doors are open, the passenger 90 will move out of the elevator car 110-1 and toward the elevator landing zone 410, the passenger 90 will be continuously away from the first wireless signal module 130-1, the signal strength of the first wireless signal (broadcast by the first wireless signal module 130-1) received by the personal mobile terminal 200 will gradually weaken from strong, such as changing from greater than or equal to a first relatively strong predetermined value, which may indicate that the passenger 90 is currently within a range of 0.7-1 meters from the first wireless signal module 130-1, to zero or weak, and the passenger 90 is likely to be located in the elevator car 110-1 when the signal strength is greater than or equal to the first predetermined value.

Thus, in one embodiment, the first wireless signal module 130-1 broadcasts the first floor information of the floor where the elevator car 110-1 is currently located via the first wireless signal all the time, e.g., during the downward travel from floor (N + x) to floor N until the elevator car 110-1 stops at floor N, the first wireless signal module 130-1 broadcasts the first floor information of (N + x) to N, and the personal mobile terminal 200 will be able to receive these changed first floor information before the landing door opens. The personal mobile terminal 200 will also be able to receive the first floor information of floor N) after the landing door is opened, while the personal mobile terminal 200 determines the signal strength of the received first wireless signal by RSSI or the like. If the signal strength of the first wireless signal received at the personal mobile terminal 200 changes from greater than or equal to a first predetermined value that is relatively strong to zero or relatively weak, and the personal mobile terminal 200 determines that the passenger has moved from the elevator car 110-1 to the landing elevator zone 410 after taking the elevator when the change occurs while the received first floor information (e.g., floor N) changes from the first floor information (e.g., floor N + 1) that it received before the change. Thus, in conjunction with the change in the first floor information, it can be determined not only that a passenger has moved from elevator car 110-1 into elevator landing zone 410, but that the passenger was riding in the elevator prior to the movement, thus distinguishing the situation where passenger 90 entered elevator car 110-1 and exited elevator car 110-1 at the same floor. When the signal strength of the first wireless signal received by the personal mobile terminal 200 changes from greater than or equal to a first predetermined value that is relatively strong to zero or is relatively weak, and the personal mobile terminal 200 does not change while the change is occurring in the received first floor information (e.g., floor N) from the first floor information (e.g., floor N) that it received before the change, it is determined that the passenger 90 has not moved from the elevator car 110-1 into the landing elevator zone 410 after taking an elevator. As an example scenario: a passenger 90 waiting to board the elevator landing zone 410 first steps into the elevator car 110-1 when the elevator car 110-1 stops, finds that the elevator car 110-1 is not the assigned elevator car (e.g., 110-2), and the passenger 90 then returns from the elevator car 110-1 to the elevator landing zone 410.

In an embodiment, the personal mobile terminal 200 or its movement determination module 250 is configured to: when the signal strength of the first wireless signal it receives changes from greater than or equal to a first predetermined value that is relatively strong to zero or is relatively weak and it changes while the received first floor information changes from the first floor information it received before the change, it is determined that the passenger 90 has moved from the elevator car 110-1 into the elevator landing zone after taking the elevator. The personal mobile terminal 200 or its movement determination module 250 is further configured to: it is determined that the passenger 90 moves from the elevator car 110-1 into the elevator landing zone but not after the passenger 90 takes the elevator, when the signal strength of the first wireless signal it receives changes from greater than or equal to a first predetermined value that is relatively strong to zero or relatively weak and when it does not change while the change is occurring with the received first floor information from the first floor information that it received before the change.

In the movement determination process or movement determination method, whether a passenger moves from the elevator car 110 toward the elevator landing zone 410 can be determined by a change in the signal strength of the received first wireless signal, and whether the passenger travels with the first elevator car 110 before leaving the elevator car can be determined by comparison with the first floor information of the previously received first wireless signal, so that it can be determined whether the passenger 90 moves from the elevator car 110-1 into the elevator landing zone 410 after taking an elevator. The first floor information of the first wireless signal received before the change above is received with the RRSI indicated as "strong", i.e., the signal strength remains greater than or equal to the first predetermined value, which further indicates that the passenger 90 receives the changed first floor information inside the elevator car 110.

As shown in fig. 1-3, in yet another alternative embodiment, the first wireless signal module 130 is coupled to the elevator controller 140, and during operation of each elevator car 110, the first wireless signal module 130 is capable of obtaining the travel direction information of the elevator car 110 from the elevator controller 140 in real time, for example, when the elevator travels upwards, the travel direction information is "traveling upwards", when the elevator travels downwards, the travel direction information is "traveling downwards", and when the elevator stops at a floor, the travel direction information is "not traveling"; and, pack the direction of travel information as the wireless data signal and broadcast out in the form of the first wireless signal.

Thus, the first wireless signal module 130-1 always broadcasts the traveling direction information through the first wireless signal, for example, the traveling direction information of "traveling down" is always broadcast by the first wireless signal module 130-1 during the downward traveling from the floor (N + x) to the floor N until the elevator car 110-1 stops at the nth floor, and the personal mobile terminal 200 before the landing door is opened will always be able to receive the traveling direction information. The personal mobile terminal 200 or its movement determination module 250 is configured to determine the movement of the passenger 90 relative to the elevator landing zone 410 based on a change in the signal strength of the received first wireless signal, and also determine whether the ride is to make the movement after riding the elevator based on a change in the direction of travel information of the received first wireless signal. In an embodiment, the personal mobile terminal 100 or its movement determination module 250 is further configured to: when the signal strength of the first wireless signal it receives changes from greater than or equal to a first, relatively strong, predetermined value to zero or relatively weak and the direction of travel information received prior to the change changes from "traveling up" or "traveling down" to "not traveling," it is determined that the passenger 90 has moved from the elevator car 110 into the elevator landing zone 410 after riding the elevator. The personal mobile terminal 100 or its movement determination module 250 is further configured to: when the signal strength of the first wireless signal it receives changes from greater than or equal to a first, relatively strong predetermined value to zero or relatively weak and the direction of travel information received prior to the change is "no travel," it is determined that the passenger 90 moved from the elevator car 110 into the elevator landing zone 410 but did not occur after the passenger 90 took the elevator.

In the movement determination process or movement determination method, it can be determined whether the passenger moves from the elevator car 110 toward the elevator landing zone 410 by a change in the signal strength of the received first wireless signal, and it can be determined whether the passenger 90 moves from the elevator car 110-1 into the elevator landing zone 410 after taking an elevator by continuing the comparison with the traveling direction information of the first wireless signal received before the movement. The first floor information of the first wireless signal received before the change above is received with the RRSI indication being "strong", i.e., the signal strength remains greater than or equal to the first predetermined value, which further indicates that the passenger 90 receives the changed direction of travel information inside the elevator car 110.

In the above embodiment, when the passenger 90 moves away from the first wireless signal module 130 from the proximity, the change of the signal strength of the first wireless signal received by the personal mobile terminal 200 becomes gradually weaker based on the transmission characteristic of the wireless signal, and therefore, the change of the signal strength of the first wireless signal from greater than or equal to the relatively strong first predetermined value to zero or relatively weak may be selected to be gradually changed, for example, a linear descending change or a gradual curve descending change. In this way, situations like "abruptly changing" in signal strength or the like that do not indicate movement of the passenger 90 from the elevator car 110 into the elevator landing zone 410 can be excluded, which is advantageous in increasing the accuracy of the determination.

It should be noted that the first predetermined value is selected to represent the signal strength value of the first wireless signal received by the personal mobile terminal 200 when the passenger is inside the elevator car or is likely to be inside the elevator car, for example, the signal strength value of the first wireless signal received by the personal mobile terminal 200 when the passenger 90 is at a certain distance in the range of 0.7-1 meter relative to the first wireless signal module 130, or the signal strength value of the first wireless signal received by the personal mobile terminal 200 when the passenger 90 is in the elevator car 110. Generally, when the landing door is closed, the personal mobile terminal 200 outside the elevator car 110 cannot receive the corresponding first wireless signal or the received first wireless signal is weak.

In this application, the weaker signal strength of the first wireless signal means that the signal strength of the first wireless signal is at least less than a first predetermined value. In the case of being less than the first predetermined value, this indicates that the passenger is or is likely not inside the elevator car 110, but in an elevator landing zone 410 outside the elevator car 110.

Continuing with fig. 1 and 2, in one embodiment, the movement-determining device 10 further includes a second wireless signal module 120 installed in each elevator landing zone 410 for broadcasting a second wireless signal, such as a data signal that always broadcasts second floor information for the elevator landing zone 410 in which the second wireless signal module 120 is located, so that the second floor information can always be received by the personal mobile terminal 200 once it enters the elevator landing zone 410. Accordingly, the personal mobile terminal 200 or its movement determination module 250 may be configured to: the movement of the passenger 90 from the elevator car 110 into the elevator landing zone 410 in which the second wireless signal module 120 is installed is determined when the signal strength of the first wireless signal it receives changes from greater than or equal to a first, relatively strong, predetermined value to zero or relatively weak and it does not receive the second floor information of the second wireless signal before the change, and after the change the second floor information of the second wireless signal received does not change relative to the first floor information of the first wireless signal it previously received.

For example, in a movement determination method or manner, if the passenger 90 leaves the elevator car 110 after taking an elevator, the landing door is typically opened and then leaves the elevator car, for example, when the elevator car 110 moves to the nth floor and stops at the nth floor, before the passenger 90 leaves the elevator car 110, the mobile terminal 200 is always capable of receiving the first wireless signal module 130-1 and always broadcasting the first floor information of the floor where the elevator car 110-1 is currently located, for example, the floor N; after the landing door is opened, the signal strength of the first wireless signal received by the personal mobile terminal 200 is changed from greater than or equal to a first relatively strong predetermined value to zero or relatively weak, the changing process indicates that the passenger 90 is in the process of moving from the elevator car 110 to the elevator landing zone 410, after the changing process, the personal mobile terminal 200 can receive the second floor information broadcasted by the second wireless signal module 120, such as the floor N, compare the second floor information with the previously received first floor information, and if the second floor information is the same, such as the floor N, the passenger 90 is determined to move from the elevator car 110 to the elevator landing zone 410 where the second wireless signal module 120 is located after taking the elevator.

The movement determining means 10 of the embodiment of the invention can also be used to determine whether a passenger moves outside the elevator landing zone. In an embodiment, the personal mobile device 200, when receiving the second wireless signal, further determines the received second wireless signal strength by the signal strength determination module 230 (e.g., RSSI), and the personal mobile device 200 or its movement determination module 250 is further configured to: when the signal strength of the second wireless signal it receives changes from greater than or equal to a second predetermined value to zero or is relatively weak, it is determined that the passenger moved substantially outside of the elevator landing zone 410. The second predetermined value can be a signal strength of a second wireless signal received corresponding to the personal mobile device 200 being located at an exit location of the elevator landing zone, or a signal strength threshold of the second wireless connection 320 automatically establishing a call request command for the passenger 90 as the personal mobile device 200 approaches the elevator landing zone 410 from outside the elevator landing zone 410.

Illustratively, in a movement determination method or manner, after a passenger 90 moves into an elevator landing 410, it is generally likely to leave that elevator landing zone 410, even a building, and in the process of exiting from the elevator landing zone 410, the passenger 90 is constantly away from the second wireless signal module 120, and therefore, the signal strength of the second wireless signal received at the personal mobile terminal 200 will vary from greater than or equal to the second predetermined value to zero or relatively weak, and if it does occur, it can be determined that the passenger 90 has moved substantially outside of the elevator landing zone 410.

Since the passenger 90 generally does not need to perform an automatic call operation when moving out of the elevator hall area 410, the personal mobile terminal 200 is also configured to: automatically entering a sleep mode upon determining that a passenger moves substantially outside of the elevator landing zone. In the sleep mode, the personal mobile terminal 200 does not automatically perform the functions of the embodiment of the present invention. The next time the passenger reenters the elevator landing zone 410, the second wireless signal that may be received by the personal mobile terminal 200 wakes up from the sleep mode so that the functions of the embodiments of the present invention may be automatically performed, e.g., again an automatic call operation.

The movement specifying device 10 according to the embodiment of the present invention can be applied to the elevator system 100 according to the embodiment of the present invention described below, which can automatically complete a call operation completely hands-free (hand free), and can effectively avoid the occurrence of an invalid call operation.

As shown in fig. 1 and 2, in order to obtain a call request command from each elevator landing zone 410, a second wireless signal module 120 is provided in the elevator system 100, and the second wireless signal module 120 can be installed in each elevator landing zone 410 of the elevator system 100 (as shown in fig. 2). It is to be understood that one or more second wireless signal modules 120 can be installed at each elevator landing zone 410 such that the second wireless signals emitted by the second wireless signal modules 120 can effectively substantially cover each elevator landing zone 410. The second wireless signal module 120 can be provided in particular integrally in a call control panel of the elevator system 100, wherein the call control panel 12 is generally installed on both sides of the landing door of the elevator landing zone 410, and call buttons, for example, "up" or "down", can be provided on the call control panel 12, so that manual entry of call request commands can also be effected on the basis of the call control panel 12.

In an embodiment, the second wireless signal module 120 may specifically be a Bluetooth Low Energy (BLE) module, and the second wireless signal may be a BLE signal, for example, which may include a wake-up signal for waking up the personal mobile terminal 200 and may further include an identity (e.g., a universally unique identifier UUID) of the second wireless signal module 120. The particular signal form of the second wireless signal is not limiting. Similarly, the signal strength of the second wireless signal is attenuated with the distance it travels, and thus, the personal mobile terminal 200 receiving the second wireless signal can roughly determine the distance of the personal mobile terminal 200 with respect to the second wireless signal module 120 according to the signal strength of the second wireless signal. It will be appreciated that the distance is dynamically changing as passengers travel in the elevator landing zone 410.

Continuing with fig. 1 and 2, the elevator system 100 also includes a plurality of first wireless signal modules 130, each first wireless signal module 130 being mounted in each elevator car 110, e.g., one first wireless signal module 130-1 disposed in the elevator car 110-1 and one first wireless signal module 130-2 disposed in the elevator car 110-2. In one embodiment, the elevator car 110 is mounted on a destination floor registration control panel and integrally disposed on the destination floor registration control panel.

It should be noted that each of the second wireless signal module 120 and the first wireless signal module 130 in the movement determination device 10 or the elevator system 100 is coupled to the elevator controller 140, for example, they are indirectly coupled (e.g., connected through an RSL bus) to the elevator controller 140 through the call control board and the destination floor registration control board, respectively, so that the call request command and the destination floor registration command received by the second wireless signal module 120 and the first wireless signal module 130, respectively, can be transmitted to the elevator controller 140.

Continuing with fig. 1, the movement determining apparatus 10 or the personal mobile terminal 200 carried by the passenger 90 in the elevator system 100 may be plural, for example, personal mobile terminals 200-1 and 200-2 carried by two passengers, respectively. Each personal mobile terminal 200 may establish a second wireless connection 320 with the second wireless signal module 120 and each personal mobile terminal 200 may establish a first wireless connection 330 with the first wireless signal module 130.

As further shown in fig. 1-3, the personal mobile terminal 200 may be various intelligent terminals with wireless connection function, which are convenient for passengers to carry; the personal mobile terminal 200 may be provided with a memory, a processor with computing function, etc., and specifically, the personal mobile terminal 200 may be a smart phone, a wearable smart device (e.g., a smart band, etc.), a personal digital assistant (PAD), etc., on which a corresponding application (e.g., APP) may be installed to implement its function.

In the elevator system 100, when the second wireless signal module 120 broadcasts the second wireless signal, the personal mobile terminal 200 carried by the passenger approaching the second wireless signal module 120 can automatically receive the second wireless signal, and based on the second wireless signal, the personal mobile terminal 200 and the corresponding second wireless signal module 120 automatically establish the second wireless connection 320; and, upon establishing the second wireless connection 320, the personal mobile terminal 200 sends a call request command regarding the call direction (e.g., an "up" or "down" call request command), the second wireless signal module 120 receives the call request command regarding the call direction sent from the personal mobile terminal 200, the second wireless signal module 120 further can send the call request command to the elevator controller 140, such that the elevator controller 140 controls the operation of one or more elevator cars 110 in the elevator system 100 based on the call request command. Therefore, the call request command automatically sent by the personal mobile terminal 200 can replace the call request command input by manually pressing a call button, and the above process can be automatically realized without the need of a passenger to operate the personal mobile terminal 200, so that the passenger can automatically input the call request command to the elevator system 100 without reaching, the realization process is simple and convenient, and the passenger experience is greatly improved.

It should be noted that, for each second wireless signal module 120, the second wireless connection 320 is established with only one personal mobile terminal 200 at a certain time, and each second wireless signal module 120 may successively establish the second wireless connection 320 with the personal mobile terminals 200 carried by a plurality of passengers approaching the second wireless signal module 120 in sequence. Each personal mobile terminal 200 establishes a second wireless connection 320 with the second wireless signal module 120 and sends a corresponding call request command, which will actively disconnect the second wireless connection 320 in preparation for the second wireless signal module 120 automatically establishing a second wireless connection 320 with the next passenger's personal mobile terminal 200. In one embodiment, the second wireless signal module 120 is configured to return a second confirmation message to the corresponding personal mobile terminal 200 after receiving the call request command, the second confirmation message indicating that the call request command was successfully accepted by the elevator system 100; the personal mobile terminal 200 is configured to actively disconnect the second wireless connection 320 based on the received second confirmation message.

It should be noted that the "call request command for a call direction" of the present invention does not include destination floor information of a passenger, or even includes destination floor information that is not recognized or used by the elevator controller 140. Therefore, in the embodiment of the present invention, the first wireless signal module 130 is also relied on to establish the first wireless connection 330 with the personal mobile terminal 200.

Continuing with fig. 1, in the elevator system 100 or the movement determining apparatus 10, when the first wireless signal module 130 broadcasts the first wireless signal, the personal mobile terminal 200 carried by the passenger 90 approaching the first wireless signal module 130 (e.g., when the passenger 90 moves toward the inside of the elevator car) will continue to be able to automatically receive the first wireless signal (when the previously established second wireless connection 320 between the personal mobile terminals 200 and the second wireless signal module 120 has been disconnected), and based on the first wireless signal, the first wireless connection 330 is automatically established between the personal mobile terminal 200 and the corresponding first wireless signal module 130; and, upon establishing the first wireless connection 330, the personal mobile terminal 200 transmits a registered destination floor command regarding destination floor information, the first wireless signal module 130 receives a call request command regarding call direction transmitted from the personal mobile terminal 200, the first wireless signal module 130 further may transmit the registered destination floor command to the elevator controller 140, such that the elevator controller 140 controls operation of one or more elevator cars 110 in the elevator system 100 based on the registered destination floor command. In this way, the destination floor registration command automatically sent by the personal mobile terminal 200 can replace the destination floor registration command input by pressing a floor button in a manual mode, and the above process can be automatically realized without the need of a passenger operating the personal mobile terminal 200, namely, the passenger can automatically input the destination floor registration command to the elevator system 100 without reaching out of hand, the realization process is simple and convenient, and the passenger experience is greatly improved.

It should be noted that, for each first wireless signal module 130, the first wireless connection 330 is established with only one personal mobile terminal 200 at a certain time, and each first wireless signal module 130 may successively establish the first wireless connection 330 with the personal mobile terminals 200 carried by a plurality of passengers 90 approaching the first wireless signal module 130 in sequence. Each personal mobile terminal 200 establishes a first wireless connection 330 with the first wireless signal module 130 and sends a corresponding destination floor registration command, which will actively disconnect the first wireless connection 330 in preparation for the first wireless signal module 130 to establish the first wireless connection 330 with the personal mobile terminal 200 of the next passenger 90. In one embodiment, the first wireless signal module 130 is configured to return a first confirmation message to the corresponding personal mobile terminal 200 after receiving the registered destination floor call, the first confirmation message indicating that the registered destination floor call was successfully accepted by the elevator system 100; the personal mobile terminal 200 is configured to actively disconnect the first wireless connection 330 based on the receipt of said first confirmation message.

It should be understood that the above-mentioned process of establishing the second wireless connection 320 to disconnecting the second wireless connection 320 can be completed in a short time, and also, the above-mentioned process of establishing the first wireless connection 330 to disconnecting the first wireless connection 330 can be completed in a short time, for example, in a time range of the order of milliseconds, so that one second wireless signal module 120 or first wireless signal module 130 can complete the second wireless connection 320 or first wireless connection 330 with the personal mobile terminals 200 in turn in a short time, and the personal mobile terminals 200 can complete the call operation in a short time at substantially the same time.

The elevator system 100 or the movement determination device 10 according to the above embodiment can achieve a completely hands-free automatic call operation, for example, when a passenger 90 carries the personal mobile terminal 200 while entering a hall of a building to reach a destination floor, the passenger can take an elevator to reach the destination floor without any operation. As shown in fig. 2, if the passenger 90 moves toward the elevator landing zone 410 in the other area of the building while the distance of the personal mobile terminal 200 from the second wireless signal module 120 in the elevator landing zone 410 is less than or equal to the second distance threshold while the signal strength of the received second wireless signal changes from zero or weak to greater than or equal to the second predetermined value, which is relatively strong, the second wireless connection 320 will establish and automatically send a corresponding call request command, based on which the elevator controller 140 will control the travel of the elevator car, e.g., control the elevator car 110-1 to stop at the floor or landing corresponding to the elevator landing zone 410. However, if a passenger 90 is a passenger 90 moving out of the elevator car 110-1 stopped at the floor into the elevator landing zone 410, the personal mobile terminal 200 carried by the passenger 90 automatically establishes the second wireless connection 320 with the second wireless signaling module 120 and sends a call request command to the second wireless signaling module 120, which obviously tends to cause inefficient operation of the elevator, affecting the operating efficiency of the elevator system 100.

In the movement determination device 10 and the movement determination method thereof according to the embodiment of the present invention, the determination result of the passenger with respect to the elevator landing zone 410 can also be transmitted to the elevator system 100. In the elevator system 100 according to an embodiment of the present invention, the determination result may be transmitted to the elevator controller 140, for example, when it is determined that the passenger 90 moves from the elevator car 110 into the elevator landing zone 410 after taking the elevator, the personal mobile terminal 200 is located in the elevator landing zone 410, and thus, the wireless communication module 210 of the personal mobile terminal 200 may actively establish a wireless connection with the second wireless signal module 120 and transmit the determination result to the elevator controller 140. The elevator controller 140 is further configured to select the determination result of the movement of the passenger 90 relative to the elevator landing zone 410 sent from the movement determination device 10 as a determination condition to determine whether or not to cancel the call request command of the personal mobile terminal 200 of the corresponding passenger 90

Illustratively, when the passenger 90 moves from the elevator car 110 into the elevator landing zone 410, the personal mobile terminal 200 automatically sends a call request command with the call direction up to the second wireless signal module 120 in the elevator landing zone 410, and simultaneously sends the movement determination result; upon receipt by the elevator controller 140 of a determination that, particularly, a passenger 90 has moved from the elevator car 110 into the elevator landing zone 410 after riding in an elevator, the elevator controller 140 will cancel or reject the call request command corresponding to the passenger with the call direction up; upon receipt of a determination by the elevator controller 140, particularly that the passenger 90 is moving from the elevator car 110 into the elevator landing zone 410, but not occurring after the passenger 90 takes the elevator, the elevator controller 140 will not cancel or will not reject the call request command for which the call direction for the passenger is up.

It should be understood that the condition for the elevator controller 140 to determine whether to cancel or reject the call request command corresponding to the passenger 90 is not limited to one condition that is the determination result transmitted from the personal mobile terminal 200, and may include other conditions as determination elements, for example, call request commands corresponding to other passengers, the current operating condition of the elevator car, and the like.

In the elevator system 100 of yet another embodiment of the present invention, the above determination may not be sent to the elevator controller 140, and alternatively, in order to avoid generating an invalid call request, the sending of a call request command is suspended in the case where it is determined that the passenger 90 moves from the elevator car 110 into the elevator landing zone 410, particularly in the case where it is determined that the passenger 90 moves from the elevator car 110 into the elevator landing zone 410 after taking the elevator. Thus, even if the personal mobile terminal 200 of a passenger 90 exiting the elevator car 110 establishes the second wireless connection 320 with the second wireless signaling module 120 in the elevator landing zone 410, the call request command is not received by the elevator system 100 if it is sent. The length of the pause can be set on a case-by-case basis, for example, based on the length of time a passenger typically takes from exiting the elevator car 110 to completely exiting the elevator landing zone 410, for example, in the range of 15 seconds to 1 minute. It will be appreciated that after this time period of suspension, the passenger 90 can continue to automatically send call request commands based on the personal mobile terminal 200.

It should be noted that the movement determination device 10 and the movement determination method thereof according to the embodiment of the present invention are not limited to the elevator system 100 capable of completely hands-free call operation according to the above embodiment, and for example, the movement determination device 10 and the movement determination method thereof may also be applied to an elevator system based on another automatic call operation method. In said other call operating mode, the personal mobile terminal can automatically send or automatically input at a time a call request command for both call direction and destination floor information to the elevator system, which will assign the passenger a corresponding elevator car based on the command (there are multiple elevator cars in the elevator system at the same time) and automatically register the passenger's destination floor in the elevator car. In such elevator systems, if a passenger 90 enters the elevator landing zone 410 from the elevator car 110, there is similarly a problem of inefficient operation of the assigned elevator car, again affecting the operating efficiency of the entire elevator system. The elevator controller 140 of such an elevator system may also be configured to select the determination result of the movement of the passenger 90 relative to the elevator landing zone 410 sent by the movement determining device 10 as a judgment condition to judge whether to cancel the call request command of the personal mobile terminal 200 of the corresponding passenger 90 or to configure the personal mobile terminal 200 to suspend sending the call request command so as to avoid an ineffective operation of the assigned elevator car 110.

In the movement determining device 10 or the elevator system 100 of the above embodiment, the first wireless signal module 130 in each elevator car 110 may always broadcast the first wireless signal, which includes one or more of the following: first floor information, direction of travel information, etc. It will be appreciated that this information is changing in real time. Likewise, the second wireless signal module 120 in each elevator landing zone 410 can always broadcast at least second floor information. The personal mobile terminal 200 or its movement determination module 250 can comprehensively determine the movement of the passenger 90 relative to the elevator landing zone 410 based on changes in a plurality of the first floor information, the second floor information, the direction of travel information, the determination of the movement may be more accurate.
